TAS Indolide and TAS Carbazolide: Structures of [TAS]+[IndHInd]? and [TAS]+[Carb]?·½CarbH From the reaction of TAS‐fluoride [(Me2N)3S]+[Me3SiF2]? with trimethylsilyl‐indole and trimethylsilyl‐carbazole TAS‐indolide and TAS‐carbazolide are formed. During crystallisation partially protonation to indole and carbazole occurs, resulting in the formation of [TAS]+[IndHInd]? ( 3a ) and [TAS]+[Carb]?·½CarbH ( 5a ) according to X‐ray analysis. 相似文献

Structures of Alkali Metal Salts of Aromatic, Heterocyclic Amides: Synthesis and Structure of Crown Ether Adducts of the Alkali Metal Indolides The synthesis of five alkali metal indolide crown ether complexes is reported. Lithium‐indolide(12‐crown‐4) ( 1 ) was synthezised from butyllithium, indole, and 12‐crown‐4; sodium‐indolide(15‐crown‐5) ( 2 ) from sodium metal, indole, and 15‐crown‐5; potassium‐indolide(18‐crown‐6) ( 3 ) from potassium hydride, indole, and 18‐crown‐6. Rubidium‐ and cesium‐indolide(18‐crown‐6) ( 4 , 5 ) were made from Rb‐ and Cs‐hexamethyldisilazide, indole, and 18‐crown‐6. The structures of 2 , 4 , and 5 could be determined by X‐ray diffraction. The complexes 2 and 4 are mononuclear, the indolide anion shows an η1(N)‐coordination to the metal cation. Complex 5 is dinuclear with a central [Cs—N—]2‐ring. 相似文献
